In fact, because Tiangong technology has successfully developed aircraft electric engines and sold a large number of them to domestic enterprises, a large number of civil electric passenger aircraft have begun to be developed in China.


    Among these enterprises, some enterprises have started the idea of developing tilt rotor airliner, and even their products have now completed the design stage and entered the actual manufacturing stage.


    However, because the technical capabilities of these enterprises can not be compared with Tiangong technology and other official enterprises, the size of these tilt rotor aircraft designed by these enterprises is relatively small, and for the sake of technical difficulty and safety, the tilt rotor aircraft selected are multi rotor aircraft with more than four rotors.


    Compared with the rotorcraft with double rotors and more than four rotors, especially the rotorcraft with more than the eighth rotor, the safety is much higher and the possibility of losing control is much smaller. After all, the technical capacity of these enterprises is limited.


    Of course, in addition to these private enterprises, official enterprises have naturally launched the research and development of tilt rotor aircraft. However, the largest size of the officially developed tilt rotor aircraft is similar to that of the owl.


    This model of Tiangong technology is different. Apart from others, just in terms of aircraft size, it is definitely not comparable to the rotorcraft of these enterprises.


    After all, the size of this aircraft is built according to the size of phoenix-1 aircraft, so the technical difficulty of tens of meters long tilt rotor aircraft, even the current Tiangong technology, is also very difficult.


    Of course, it may seem to many people that the research and development of this large tilt rotor aircraft is not good for Tiangong technology. After all, the technical difficulty of large tilt rotor aircraft is so high, and the cost of research and development is also very high.


    However, Wang Bin and Tiangong science and Technology aerospace aviation laboratory do not think so. First of all, naturally, if there are large aircraft that can take off and land vertically, these aircraft have great uses in many aspects, especially in rescue and disaster relief.


    In addition, the reason why Tiangong technology will carry out the research and development of this kind of aircraft actually has its own consideration, that is, to verify the feasibility of the vertical takeoff and landing technology of large aircraft.


    You know, like the Phoenix kt1 aircraft, as an aerospace aircraft, it is doomed that it will not only go back and forth between the earth and low earth orbit in the future. In addition, this aircraft will also undertake various flight missions in the Earth Moon space system, that is, the means of transportation between various space manned spacecraft in the Earth Moon space system, The aircraft will also be used as a spacecraft vehicle between the moon and lunar orbiting spacecraft.


    However, landing on the moon is different from landing on the earth. There is no atmosphere on the moon. Therefore, on the moon, the wing of the aircraft has no use at all. Even because of the existence of the wing, it brings more harsh conditions for landing.


    Therefore, if an aerospace plane wants to land on the moon, it can only be realized by an engine on an aircraft.


    However, this brings a new problem, that is, when the plane lands on the moon, it can''t land upside down. If it''s OK in the process of landing.


    However, if the tail first landing is carried out during landing, the risk can be imagined.


    Therefore, at this time, the method of vertical takeoff and landing is undoubtedly the best method.


    Therefore, Tiangong technology has already started the exploration and R & D of large-scale flight control vertical take-off and landing technology, and has also made great achievements.


    However, when relevant laboratories have developed VTOL technology for large aircraft, there is no physical object to verify,


    After all, the difference between vertical takeoff and landing aircraft and ordinary aircraft is too big, and even if this technology is successfully verified on ordinary large aircraft, it may not be used in Phoenix series.


    Finally, Wang Bin and others decided to develop an improved version of the Phoenix, which was specially used to verify the technology in the atmosphere.


    If the verification is successful, then Tiangong technology will replace the electric turbofan engine on the aircraft with a pulse detonation rocket engine for verification.


    Finally, if it is also successful, when it is really necessary to land on the moon, Wang Bin and they can fully develop the vertical takeoff and landing model of phoenix-1 series that can be specially used for lunar landing.


    It is based on the consideration of so many factors that Wang Bin and his team have made great efforts to develop this vertical takeoff and landing Phoenix -cz1 aircraft.


    Now, the drawing design of this technology verification machine is almost the same, only the final drawing verification stage is missing.


    "Mr. Wang! The drawing design of our phoenix-zc1 vertical takeoff and landing aircraft has basically been carried out. The design of all parts of the aircraft has been completed. Can the workshop start the trial production of parts?" Professor Dai of the aircraft design department asked Wang Bin.


    In fact, the most important purpose of Wang Bin''s visit today is to review the design drawings of the aircraft and find some defects of the aircraft.


    However, today''s Tiangong technology is not Tiangong technology in the past. When designing aircraft, it is natural that these designers in the design department have strong ability. Secondly, in the design process, they are assisted by supercomputers and intelligent systems. In the aircraft design process, countless computer simulations are carried out, Therefore, even if Wang Bin has countless knowledge of aircraft design in his mind, he can''t find the design defects of this aircraft.


    Therefore, after Wang Bin reviewed the drawings of the aircraft, Professor Dai asked Wang Bin.


    "It''s time to start manufacturing parts. Professor Dai, do you think it''s ok? Now that we''ve started production, let''s just produce more prototypes." after listening to Professor Dai''s words, Wang Bin nodded and said.


    "Yes! In this way, in the future test flight, the progress can be faster." after that, he thought for a while and said, "just produce five! After all, it''s not good to produce too many at once!"


    "Yes!" Wang Bin nodded.


    Immediately, Wang Bin used his authority in the company''s intelligent computer to distribute the production of various parts in the drawings. As for the parts and equipment not produced by Tiangong technology, Wang Bin also assigned these parts to the procurement department and asked the procurement department to purchase with relevant manufacturers.


    At the same time, after Wang Bin distributed the production of these parts, countless intelligent machine tools automatically added these parts to the production directory in the precision machining workshop.


    At the same time, the processing master of the machine tool also received a reminder from the computer to arrange the processing of these parts as soon as possible.
